Fixed Wing Flight Controls Review Flashcards
What are the characteristics of primary surfaces?
Movable surfaces, cause an aircraft to rotate on its three axes.
Where are Ailerons located and what do they control?
on the trailing edge of each wing near the tip: Control roll around the longitudinal axis. (wings up or down)
Where are elevators located and what do they control?
the trailing edge of the horizontal stabilizer: controls movement on the lateral axis. (Nose up/nose down)
Where are rudders located and what do they control?
the trailing edge of the vertical stabilizer, controlled by rudder pedals: rotates aircraft around the vertical axis. (turns left and right)
What is the purpose of auxiliary surfaces?
Lift modifying devices on an airfoil.
Where are flaps located and how do they modify lift? What does this modification allow?
Flaps are on the trailing edge of the wing nearest the fuselage: provide greater lift at low speeds and high angles of attack. Reduces landing speed, shortens the length of the landing roll and increases lift for takeoff.
What are the two types of flaps used in CG aviation?
Fowler flap and the Slotted flap
Where are slats located and how do they modify lift? What does this modification allow?
Slats are on the leading edge of the wing, closest to the fuselage: used in conjunction with flaps. Allows aircraft to fly at lowered speeds for takeoff, landings, and are used for stall avoidance.
Where are air brakes located and how do they modify lift? What does this modification allow?
Airbrakes may be located on fuselage or the wings: Slows the speed of the aircraft when descending at steep angles such as approaching the runway.
What is the purpose of second flight controls?
Assist the pilot in moving the primary control surfaces or trim out of balance conditions.
What are some examples of secondary flight controls?
Trim tabs, servo tabs, and spring tabs are attached to the trailing edge of the primary control surfaces
